The Echo1 M4 Boxmag is the highest capacity magazine you can get for an M4 AEG. These 5000 round box magazines will fit standard M4 airsoft guns. If you're looking for something to keep you in the game without reloading, or want to lay down heavy fire, these box magazines are ideal.

Fits most brand M4 or M16 AEGs. May not fit some other rifles which are STANAG compatible due to outside dimensions.
